Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480180, here are decompositions:

53 + 33480127 = 33480180
61 + 33480119 = 33480180
103 + 33480077 = 33480180
127 + 33480053 = 33480180
137 + 33480043 = 33480180
157 + 33480023 = 33480180
179 + 33480001 = 33480180
191 + 33479989 = 33480180

Showing the first eight; more decompositions exist.
